Definition: UAV mold is a variety of molds and tools used in industrial production to obtain the products needed by injection molding, blow molding, die casting and other methods. Classification: According to the processing technology and processing objects, UAV molds can be divided into metal processing molds and non-metal processing molds. Among them, plastic molds are more common in non-metallic molds, especially suitable for the manufacture of drone shells

The shell of the sweeping robot is usually made of plastic or metal. The plastic shell is relatively lightweight and the price is relatively low, which is suitable for general family use. The metal shell is more durable, but the price is relatively high, and it is more suitable for users who have higher requirements for durability.

Power tools are the most widely used tool products in hardware tools. There are many brands and the quality is uneven. How to distinguish the quality of a power tool product? A good power tool product needs to meet the following requirements: 1. Good work performance, the necessary conditions for the use of power tools, 2, sufficient service life, service life is also an important indicator to measure the quality of a power tool product, power tools used under the same working conditions

The power tool casing is mainly composed of three materials, aluminum or plastic or iron. Common faults and solutions of the power tool casing 1. It is broken and generally needs to be replaced. When the machine cannot be purchased from the outside, it can be repaired with a plastic welding torch. 2. At the bearing If it is worn out, it is generally necessary to replace it with a new one. If it cannot be purchased, it can be tinned on the outer ring of the bearing. The rotor and stator are not swept

The superscript on the power tool housing is a double-layer insulation mark. Double insulation refers to insulation that has both working insulation (basic insulation) and protective insulation (additional insulation). Insulation is the insulation used to prevent electric shock when the working insulation is damaged.

The shell of the power tool is charged mainly in the following three ways: 1. Internal leakage There must be a conductor inside the power tool shell, and if there is a conductor, the insulation may be damaged - after the insulation is damaged, voltage leakage will naturally occur. situation. And the more serious the damage, the more serious the leakage. This kind of direct leakage is quite special.
